  • Patent number: 11437404
    Abstract: A FET IC structure made using a back-side access process that mitigates or eliminates thermal conductivity problems. In some embodiments, electrically-isolated thermal paths are formed adjacent the FET and configured to conduct heat laterally away from the FET to generally orthogonal thermal pathways, and thence to thermal pads externally accessible at the “top” of the completed IC. In some embodiments having a thermally-conductive handle wafer, electrically-isolated thermal paths are formed adjacent a FET and configured to conduct heat laterally away from the FET. Thermal vias are formed sufficiently so as to be in thermal contact with the handle wafer and with the conventional metallization layers of the device superstructure, at least one of which is in thermal contact with the lateral thermal paths. In some embodiments, the lateral thermal paths may use dummy gates configured to conduct heat laterally away from a FET to generally orthogonal thermal pathways.

  • Patent number: 11428804
    Abstract: To provide a vehicle detection system capable of detecting a preceding vehicle traveling ahead of an own vehicle based on a position of an object by using an electromagnetic wave sensor while suppressing erroneous detection, an ECU determines if first and second positions detected by a millimeter wave radar are included in the same vehicle. The ECU designates calculated information of the preceding vehicle detected based on the first position as a calculation result if it determines that detection of the preceding vehicle is made based on the first position. The ECU uses calculated information of the preceding vehicle detected based on the second position as the calculation result when it determines that detection of the vehicle is not made based on the first position but the first and the second positions had been determined in the past as detected in the same vehicle.
